Dev-Audio’s Microcone: A Novel New USB Conference Microphone

Many thanks to self-described Blogalyst Dave Michels for pointing out a new usb conference microphone from Dev-Audio called the Microcone. Featuring six microphones and some on-board DSP this little device is purportedly able to capture the directional cues inherent in a meeting.

The company sells a related OSX application that is said to record six tracks in parallel. Each track corresponds to one of the size directional microphone pickups.

According to the companies web site:

“Microcone® uses innovative intellectual property based on microphone array techniques. Microphone arrays consist of multiple microphones functioning as a single directional input device: essentially, an acoustic antenna. Using sound propagation principles, the principal sound sources in an environment can be spatially located and distinguished from each other. While the Microcone device can be understood conceptually as a single intelligent group microphone, in fact it is a microphone array device containing several microphone elements acting in an integrated manner.”

They’re leveraging acoustic beamforming, something that I have mentioned a few times in the past.

Inflexibility: TelyHD, Biscotti & Microphones

This is a semi-rant on a somewhat common theme for me, getting the best audio quality. In pondering these two new video calling devices from Tely Labs and Biscotti one thing stands out as unfortunate…they both rely exclusively upon an array of microphones built into their respective device. I find this to be short-sighted and unnecessarily inflexible.

Consider of you will the sample video that Jim Courtney recorded speaking with a gentleman from Tely Labs. The video quality is good. The audio quality is good…but it could be a lot better.

At both ends of the call there’s considerable room tone. In particular you can clearly hear that the conference room at Tely Labs is a simple drywall box. It sounds boomy and reverberant.

As I have described elsewhere, I find that the use of a speakerphone is always a last resort. It’s really only appropriate when you have a group of people collected for a call. To use a speakerphone when the call is just on-to-one is to permit the ambient noise and nature of the room to have undue influence in the audio quality.

Powerless At FAT: What’s Wrong With This Picture?

Last week I had occasion to spend several days in Fresno CA. Their airport code is FAT. But FAT is not PHAT. In fact, it’s powerless.

Like many places in the country Fresno is busily enhancing their airport. The terminal from which I arrived and departed looks like a brand new building.

The terminal had all the traditional conveniences; public restrooms, a few places to eat & drink. Of course it had seating for all the waiting passengers. It has free, but very slow, internet access via wifi. What it lacked was sensible access to AC power for people using their personal electronics.

The Belkin Conserve Valet: Dishonorably Discharged?

valet-charge-smartIn recent years the number of devices that we need to charge daily has constantly grown. Initially it was just our two cell phones. Since they each had unique power connectors each had its own AC adapter that lived near the appropriate night stand. Simple enough. Tidy even.

My Blackberry Bold 9700 was the first cell phone I used the featured the newly common micro-USB power connector. Shortly thereafter we added a Barnes & Noble Color Nook. Both of those devices require high-current chargers, where “high-current” means more than the 500 mA that is actually part of the USB standard.

That’s when things started getting more complicated. We may have achieved standardization of connectors, but still required dedicated chargers for some devices.
